OBJECTIVES: To evaluate endoscopic push-through technique cartilage myringoplasty results. METHODS: This prospective study was performed on patients with anterior tympanic membrane perforations and endoscopic push-through technique cartilage myringoplasty was performed between 2011 and 2013. The patients who did not have any cholesteatoma or otorrhea in the previous 3 months, and had an air bone gap < or =25 dB in their preoperative audiograms were included in the study. They were followed up with endoscopic examination and audiograms at 2nd, 6th, 12th, and 24th postoperative months. Pure tone averages were calculated at 0.5, 1, 2, and 4 kHz frequencies. RESULTS: Of 32 patients, 19 were females and 13 were males. The mean age was 40.3 years (range, 16 to 62 years), and the mean follow-up period was 12.4 months (range, 6 to 24 months). Graft success rate was 87.5% in this study. Preoperative mean air conduction hearing threshold was 25.9 dB, and the mean air-bone gap was 11.9 dB while these values improved to 19.5 dB and 5.3 dB respectively in the postoperative period. The mean hearing gain was 6.4 dB. The analysis of preoperative and postoperative mean air conduction thresholds and air bone gap values of the patients revealed statistically significant differences. CONCLUSION: Underlay cartilage myringoplasty with endoscopic push-through technique in anterior quadrant tympanic membrane perforations is an effective, minimally invasive and feasible method.

PURPOSE: The aim of study was to determine the level of the radiation exposure of surgical staff during surgical probe applications in breast cancer. METHODS: Three operations of a sentinel lymph node biopsy were randomly selected. Spaced circles (50 cm apart) were drawn surrounding the operation bed on the floor. Tc-99m nanocolloid was injected peritumorally and intradermally into a patient. The radiation dose was measured with a GeigerMueller counter placed according to the drawn circles at distances of 50-200 cm from the side of patient's head and bilateral chest while the patient lay on the operation bed. All of the surgical procedures were recorded with a video camera and were monitored. RESULTS: The whole body dose to the senior surgeon was calculated as 2.00-4.70 microSv which means that a senior surgeon can perform 212-500 procedures per year to reach the annual International Commission on Radiological Protection radiation dose limit for a member of the public. CONCLUSION: We concluded that radiation risk to the surgical staff is low from sentinel node detection with the use of radiocolloids.
